<div><p>This image illustrates how a job can use multiple commitment definitions.</p>
|
|
<div class="section">The illustration is as follows:</div>
|
|
<ol><li><span>The job calls program MAIN. Program MAIN runs within the Default
|
|
Activation Group.</span></li>
|
|
<li><span>Program MAIN issues a Start Commitment Control (STRCMTCTL) command
|
|
with a lock level (LCKLVL) of *ALL.</span></li>
|
|
<li><span>The Commit Scope (CMTSCOPE) parameter is not specified. Therefore
|
|
the commitment definition for program MAIN by default is scoped to the Default
|
|
Activation Group (*DFTACTGRP).</span></li>
|
|
<li><span>Program MAIN updates files F1 and F2.</span></li>
|
|
<li><span>Program MAIN calls program PGMX. Program PGMX runs within Activation
|
|
Group X.</span></li>
|
|
<li><span>Program PGMX issues a STRCMTCTL command with LCKLVL
|
|
(*CHG). The CMTSCOPE parameter specifies the *JOB value. Therefore the commitment
|
|
definition for program PGMX is scoped to the job.</span></li>
|
|
<li><span>Program PGMX updates files F3 and F4.</span></li>
|
|
<li><span>Program PGMX calls program PGMY. Program PGMY runs within Activation
|
|
Group Y.</span></li>
|
|
<li><span>Program PGMY issues a STRCMTCTL command with LCKLVL (*CHG). The
|
|
CMTSCOPE parameter is not specified. Therefore the commitment definition for
|
|
program PGMY by default is scoped to Activation Group Y.</span></li>
|
|
<li><span>Program PGMY updates files F5 and F6.</span></li>
|
|
<li><span>Program PGMY detects an error and rolls back files F5 and F6. (The
|
|
image displays "1=ROLLBACK").</span></li>
|
|
<li><span>Program PGMY updates files F5 and F6 again and commits them. (The
|
|
image displays "2=COMMIT").</span></li>
|
|
<li><span>Program PGMY returns control to program PGMX.</span></li>
|
|
<li><span>Program PGMX calls program PGMZ. Program PGMZ runs within Activation
|
|
Group Z. Program PGMZ does not issue a STRCMTCTL command.</span></li>
|
|
<li><span>Program PGMZ updates file F7 and returns control to program PGMX.</span></li>
|
|
<li><span>Program PGMX commits files F3, F4, and F7 and returns control to
|
|
program MAIN. (The image displays "3=COMMIT").</span></li>
|
|
<li><span>Program MAIN commits files F1 and F2. (The image displays "4=COMMIT").</span></li>
